Recent studies of vocal development in infants have shed new light on old questions of how the speech capacity is founded and how it may have evolved in the human species. Vocalizations in the very first months of life appear to provide previously unrecognized clues to the earliest steps in the process by which language came to exist and the processes by which communicative disorders arise. Perhaps the most interesting sounds made by infants are the uniquely human 'protophones' (loosely, 'babbling'), the precursors to speech. Kimbrough Oller argues that these are most profitably interpreted in the context of a new infrastructural model of speech. The model details the manner in which well-formed speech units are constructed, and it reveals how infant vocalizations mature through the first months of life by increasingly adhering to the rules of well-formed speech. He lays out many advantages of an infrastructural approach. Infrastructural interpretation illuminates the significance of vocal stages, and highlights clinically significant deviations, such as the previously unnoticed delays in vocal development that occur in deaf infants. An infrastructural approach also specifies potential paths of evolution for vocal communicative systems. Infrastructural properties and principles of potential communicative systems prove to be organized according to a natural logic--some properties and principles naturally presuppose others. Consequently some paths of evolution are likely while others can be ruled out. An infrastructural analysis also provides a stable basis for comparisons across species, comparisons that show how human vocal capabilities outstrip those of their primate relatives even during the first months of human infancy. The Emergence of the Speech Capacity will challenge psychologists, linguists, speech pathologists, and primatologists alike to rethink the ways they categorize and describe communication. Oller's infraphonological model permits provocative reconceptualizations of the ways infant vocalizations progress systematically toward speech, insightful comparisons between speech and the vocal systems of other species, and fruitful speculations about the origins of language.
A comprehensive account of the neurobiological basis of language, arguing that species-specific brain differences may be at the root of the human capacity for language. Language makes us human. It is an intrinsic part of us, although we seldom think about it. Language is also an extremely complex entity with subcomponents responsible for its phonological, syntactic, and semantic aspects. In this landmark work, Angela Friederici offers a comprehensive account of these subcomponents and how they are integrated. Tracing the neurobiological basis of language across brain regions in humans and other primate species, she argues that species-specific brain differences may be at the root of the human capacity for language. Friederici shows which brain regions support the different language processes and, more important, how these brain regions are connected structurally and functionally to make language processes that take place in milliseconds possible. She finds that one particular brain structure (a white matter dorsal tract), connecting syntax-relevant brain regions, is present only in the mature human brain and only weakly present in other primate brains. Is this the “missing link” that explains humans' capacity for language? Friederici describes the basic language functions and their brain basis; the language networks connecting different language-related brain regions; the brain basis of language acquisition during early childhood and when learning a second language, proposing a neurocognitive model of the ontogeny of language; and the evolution of language and underlying neural constraints. She finds that it is the information exchange between the relevant brain regions, supported by the white matter tract, that is the crucial factor in both language development and evolution.
The central assertion in this volume is that the young child uses general skills, scaffolded by adults, to acquire the complex knowledge of sound patterns and the goal-directed behaviors for communicating ideas through language and producing speech. A child’s acquisition of phonology is seen as a product of her physical and social interaction capacities supported by input from adult models about ambient language sound patterns. Acquisition of phonological knowledge and behavior is a product of this function-oriented complex system. No pre-existing mental knowledge base is necessary for acquiring phonology in this view. Importantly, the child’s diverse abilities are used for many other functions as well as phonological acquisition. Throughout, an evaluation is made of the research on patterns of typical development across languages in monolingual and bilingual children and children with speech impairments affecting various aspects of their developing complex system. Also considered is the status of available theoretical perspectives on phonological acquisition relative to an emergence proposal, and contributions that this perspective could make to more comprehensive modeling of the nature of phonological acquisition are proposed. The volume will be of interest to cognitive psychologists, linguistics, and speech pathologists.
How well have classic ideas on whole-word phonology stood the test of time? Waterson claimed that each child has a system of their own; Ferguson and Farwell emphasized the relative accuracy of first words; Menn noted the occurrence of regression and the emergence of phonological systematicity. This volume brings together classic texts such as these with current data-rich studies of British and American English, Arabic, Brazilian Portuguese, Finnish, French, Japanese, Polish and Spanish. This combination of classic and contemporary work from the last thirty years presents the reader with cutting-edge perspectives on child language by linking historical approaches with current ideas such as exemplar theory and usage-based phonology, and contrasting state-of-the-art perspectives from developmental psychology and linguistics. This is a valuable resource for cognitive scientists, developmentalists, linguists, psychologists, speech scientists and therapists interested in understanding how children begin to use language without the benefit of language-specific innate knowledge.
The progression from newborn to sophisticated language user in just a few short years is often described as wonderful and miraculous. What are the biological, cognitive, and social underpinnings of this miracle? What major language development milestones occur in infancy? What methodologies do researchers employ in studying this progression? Why do some become adept at multiple languages while others face a lifelong struggle with just one? What accounts for declines in language proficiency, and how might such declines be moderated? Despite an abundance of textbooks, specialized monographs, and a couple of academic handbooks, there has been no encyclopedic reference work in this area--until now. The Encyclopedia of Language Development covers the breadth of theory and research on language development from birth through adulthood, as well as their practical application. Features: This affordable A-to-Z reference includes 200 articles that address such topic areas as theories and research tradition; biological perspectives; cognitive perspectives; family, peer, and social influences; bilingualism; special populations and disorders; and more. All articles (signed and authored by key figures in the field) conclude with cross reference links and suggestions for further reading. Appendices include a Resource Guide with annotated lists of classic books and articles, journals, associations, and web sites; a Glossary of specialized terms; and a Chronology offering an overview and history of the field. A thematic Reader’s Guide groups related articles by broad topic areas as one handy search feature on the e-Reference platform, which includes a comprehensive index of search terms. Available in both print and electronic formats, Encyclopedia of Language Development is a must-have reference for researchers and is ideal for library reference or circulating collections. Key Themes: Categories Effects of language on cognitive development Fundamentals, theories and models of language development Impairments of language development Language development in special populations Literacy and language development Mechanisms of language development Methods in language development research Prelinguistic communicative development Social effects in language acquisition Specific aspects of language development

This book explores the origin and evolution of speech. The human speech system is in a league of its own in the animal kingdom and its possession dwarfs most other evolutionary achievements. During every second of speech we unconsciously use about 225 distinct muscle actions. To investigate the evolutionary origins of this prodigious ability, Peter MacNeilage draws on work in linguistics, cognitive science, evolutionary biology, and animal behavior. He puts forward a neo-Darwinian account of speech as a process of descent in which ancestral vocal capabilities became modified in response to natural selection pressures for more efficient communication. His proposals include the crucial observation that present-day infants learning to produce speech reveal constraints that were acting on our ancestors as they invented new words long ago. This important and original investigation integrates the latest research on modern speech capabilities, their acquisition, and their neurobiology, including the issues surrounding the cerebral hemispheric specialization for speech. Written in a clear style with minimal recourse to jargon the book will interest a wide range of readers in cognitive, neuro-, and evolutionary science, as well as all those seeking to understand the nature and evolution of speech and human communication.
Contributors present the latest information on both the new world evolving for deaf & hard-of-hearing children & the improved expectations for their acquisition of spoken language.
This book attempts to address an interrelated set of issues about the emergence of linguistic abilities in the child. The various chapters intend to shed light on a particular and critical period in language development: the first three years of life. It is generally assumed in the field of the ontogeny of language that the child's first years of life are particularly crucial. This period is even sometimes considered as predictive at least in the short term, of the later abilities to communicate. During these first three years, gestures, phonetico-phonological, lexical and morpho-syntactic skills chronologically emerge. The main goal of this book is to address the issue of continuity between the developments of the different language components, by the means of recent findings of experts in each domain. Furthermore, the originality of this selection of chapters is to broaden the scope of the discussion by including papers dealing with related phenomena but from different perspectives such as phylogeny, pathology and animal communication. This book primarily concerns graduate students and researchers in the field of language acquisition but the audience can also include scholars from evolution of language, language pathology, animal communication, ontogeny/phylogeny research fields.
